Phenylmalonic Acid

The ionization constants of p-nitrophenylacetic and phenylmalonic acids have been determined from conductivity data. The value of K for p-nitrophenylacetic acid at 25 °C. is 1.04 × 10−4, about twice that of phenylacetic acid. The nitro group in the nucleus has not as powerful an effect on the ionization when the COOH group is in the side chain as it has when both nitro group and COOH are in the nucleus. K for p-nitrobenzoic acid is six times as great as K for benzoic acid. K for phenylmalonic acid is 2. 77 × 10−3 as compared with 1.6 × 10−3 for malonic acid.

In the title hydrated molecular salt, C8H12N+·C6H4NO3−·H2O, the conformation of the side chain in the cation isanti[C—C—C—N = 179.62 (12)°] and the dihedral angle between the aromatic ring and the nitro group in the anion is 3.34 (11)°. In the crystal, the components are linked by O—H...O and N—H...O hydrogen bonds, generating (10-1) sheets, which featureR44(21) loops. The sheets interact by weak aromatic π–π stacking interactions [centroid–centroid distance = 3.896 (3) Å], forming a three-dimensional network.
